WRENCH FOR SCREW CAPS OF JARS AND BOTTLES Filed April 25, 1931 Patented July 4, 1933 UNiTED STATES- PATENT OFFICE ,TQHNE. BEVINGTON, OF CLEVELAND, AND BRENNAN B. WEST, OF CLEVELAND HEIGHTS, OHIO WRENCH FOR SCREW CAPS OF JARS AND BOTTLES Application filed April- 25,

This invention relates to an implement or wrench for use in loosening and tightening screw caps of jars and bottles. Its ob ects are to provide a simple and inexpenslve device of this nature that is quickly and conveniently adjustable to screw caps of all sizes; that may with equal facility be applied to caps of different sizes, and that will grasp the capwith uniform pressure throughout its circumference and without danger of injury thereto, no metal parts of the implement coming in contact with the cap during the operation.

Other objects and advantages will appear as we proceed to describe our invention in detail by reference to the accompanying drawing wherein Fig. 1 is a perspective view of our improved implement applied to the cap of a jar; Fig. 2 is a plan View of the same with the implement partly in section; and Fig. 3 is a sectional detail on the line 33 of Fig. 2. I

According to our present preferred construction, the implement consists of opposed '1 plates 1 and 2, the former being constituted of an integral part of a handle or lever 3 which, for convenience, is equipped with a hook 4 for removing bottle caps of the crimped-on type.

Supported by and between opposed parts or corners of the plates 1 and 2 is an anchorage means 5 which is shown as consisting of a tubular member mounted on a screw that passes freely through one of the plates and is threaded into the other, as is best shown in Fig. 3.

Spaced laterally, with respect to the longi-' tudinal axis of the handle or lever 3, from the anchorage means 5 is a roller 6 that floats, so to speak, on a shouldered pin 7 that has its opposite ends riveted in the opposed plates 1 and 2. In spaced relation to the roller 6 is a post 8 that is rigidly supported by and between the plates 1 and 2.

10 is a flexible member, preferably made of a corded rubber, or rubber coated or impregnated fabric, which has a loop or eye 11 at one end that embraces the anchorage means 5, and a remote portion of the mem- 19315 SeriaLNo. 532,782.

ber is adapted to be engaged between the roller 6 and post 8.

When the implement is in condition for use, the fiexiblemember 10 extends between the roller 6 and post 8 so that the portion of the member between the roller. and the anclamped between the cap Aand the roller 6,

and between said roller and the post 8. Assuming that the cap has a right hand thread, and that it is desired to loosen the cap, the implement is applied in the manner shown in Figs. 1 and 2. Now by swinging the lever to the right, the portion of the member that encircles the cap is drawn into firm frictional contact therewith and the member is placed under tension, the portions between the floating roller 6 and the adjacent part of the cap A and between said roller and the post 8 being tightly pinched or clamped.

Further swinging of the lever to the right i11- substantially the plane of the cap, while holding the jar B against turning, will result in loosening the cap. To tighten acap having a right hand thread, the implement and operation are reversed, as will be readily understood.

Attention is directed to the fact that the flexible member 10 is sufliciently thick, and the roller 6 and anchorage means 5 are spaced closely enough to the edges of the plates 1 and 2 adjacent the cap A, to prevent said plates from coming in contact with the cap.

Having thus described my invention, what I claim is:

1. A cap wrench comprising a lever, a flexible member having one of its ends anchored thereto, and two spaced elements carried by the lever and between which a part of said member is adapted to be clamped, the portion of the member between said part and its anchored end constituting a loop that is adapted to be engaged about a cap, the

aforesaid elements being spaced one further than the other from the cap, the one nearest the cap being movable toward and from the other.

2. A cap wrench comprising opposed plates and a lever fixed with respect thereto, anchorage means supported by and between said plates, a flexible member having one of its ends secured to said means, a pin extending between the plates and spaced laterally, with respect to the longitudinal axis of the lever, from the anchorage means, a roller mounted for lateral play upon said pin, and a post supported by and between said plates in spaced relationto the roller and between which and the roller a part of said member is adapted to be engaged.

3. A cap wrench comprising opposed plates and a lever fixed with respect thereto, anchorage means extending between said plates, a flexible member having an eye at one end that encircles said anchorage means, a pin extending between the plates and spaced laterally from the anchorage means with respect to the longitudinal axis of the lever, a roller on said pin, and a post extending between the plates in spaced relation to said roller and between which and the roller a part of said member is adapted to be engaged, the plates being permanently connected together and spaced apart by said pin and post, and the anchorage means being readily removable whereby to provide for easy replacement of the flexible member.

4. A cap wrench comprising opposed plates and a lever fixed with respect thereto, anchorage means supported by and between said plates, a flexible member having one of its ends secured to said means, a pin extending between the plates and spaced laterally from the anchorage means with respect to the longitudinal axis of the lever, a roller mounted'on said pin and whose internal diameter is greater than the external diameter of the pin whereby the roller is capable of lateral movement on the pin, and a post supported by and between the plates in spaced relation to said roller and between which and said roller a part of the member is adapted to be engaged.

In testimony whereof, we hereunto affix our signatures.
